In some demonstrative embodiments, for example, for the short GI, a length of the data block in the SC symbol block may be extended to 480 chips, for example, for a SC symbol block having a length of 512 chips (samples), e.g., as described below.

In some demonstrative embodiments, for example, for the long GI, a length of the data block in the SC symbol block may be reduced to 384 chips, for example, for a SC symbol block having a length of 512 chips (samples), e.g., as described below.

In some demonstrative embodiments, a SC block including a GI length of 32 samples (chips), e.g., N_(GI)=32, and a SC symbol block length of data, e.g., N_(DATA)=480, may be defined for a first GI type, e.g., the short GI type, e.g., as described below.

In some demonstrative embodiments, the Golay sequences of lengths 96, 192, and 384 may be obtained, for example, from the Golay sequences defined above.

In some demonstrative embodiments, one or more requirements or design rules may be defined to create a set of Golay sequences Ga^(i) _(N) corresponding to the stream number i=1:NSTS, e.g., as follows:

-   -   1. All sequences Ga^(i) _(N) in the set of fixed length N should         have the same delay vector Dk for the Golay generator and differ         by the weight vector Wk only;     -   2. The delay vector of a longer Ga sequence may be obtained by         direct extension, for example, by adding a new delay and         preserving the rest of previous delays;     -   3. A legacy sequence Ga₆₄ may be a part of the set, for example,         to provide a consistency to a legacy IEEE 802.11ad Standard;     -   4. All sequences Ga^(i) _(N) in the set may be mutually         orthogonal; and/or     -   5. A “nested” property Ga^(i) _(N)=[Gb^(i) _(N/2), Ga^(i)         _(N/2)], Gb^(i) _(N)=[−Gb^(i) _(N/2), Ga^(i) _(N/2)] may be         satisfied for all lengths, for example, to support the aligned         symbol structure, e.g., as described above with reference to         FIGS. 3 and/or 6.

In some demonstrative embodiments, the delay vector Dk may be defined, for example, based on the Golay sequence length, e.g., as follows:

Ga^(i) ₃₂: Dk=[2 1 4 8 16];

Ga^(i) ₆₄: Dk=[2 1 4 8 16 32];

Ga^(i) ₁₂₈: Dk=[2 1 4 8 16 32 64];

Ga^(i) ₂₅₆: Dk=[2 1 4 8 16 32 64 128]; and/or
